WEIGHT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 502,814, dated August8, 1893.

Application iiled June 17, 1893.

To all whom it may concern:

Be it known that I, DIEDRICK J. FREEsE, a citizen of the United States,'residing at Higginsville, in the county of Lafayette and State ofMissouri, have invented a new and useful Weight-Motor, of whichthefollowing is a specication.

The invention relates to improvements in weight motors.

The object of the present invention is to improve the construction ofweight motors, and to provide simple and effective means, whereby heavyweights may be easily and quickly elevatedfor the purpose of furnishingthe motive power.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a side elevation of aweight motorconstructed in accordance with this invention. Fig. 2 is a verticallongitudinal sectional view.

Like numerals of reference indicate corresponding parts in both thefigures of the drawlngs.

1 designates a main frame, provided at the back with a verticalextension 2, forming a well or way for weights 3 and 4; the main framehas journaled on it a power shaft 5, which carries a drum 6; andextending from the drum are cables 7 and 8, which pass over pulleys 9and 10 and are connected to the weights 3 and 4. The cable 7 extendsupward from the front side of the drum to the top of the weight well orway; and the other cable 8 extends downward from the rear side of thedrum and passes around a pulley roll 11 and then upward to the pulleylO. This arrangement of cables equalizes the strain on the drum andenables heavy weights to beemployed without racking or straining thegearing. A train of gear wheels 12 connects the power shaft 5 with adrive shaft 13; and the latter is connected by a train of gear wheels 14with a governor 15, which regulates the speed of the motor and thedistribution of the power. The drive-shaft 13 carries a drive pulley 16from which motion may be commu- Serial Na. 477,935. (No model.)

nicated to any machinery, and one or more drive-wheels or pulleys may beemployed. The drum 6 is connected with the lowermost gear wheel 17 ofthe train 12, by a clutch consisting of a check pawl 18 and aratchetwheel 19, whereby the gear wheel 17 rotates with the drum whenthe latterk is actuated by the weights. The weights are wound up byalever 20 and a platform 21, which are fulcrumed on the main frame, andare connectedby a rod 22. The lever and the platform are provided attheir rearends with longitudinal slots 23 and 24 to enable them to beadj usted longitudinally to regulate the lifting power; and the rod 22is provided at its ends with clips 25, and is attached to the lever inadvance of the fulcrum 26, and to the platform in rear of the fulcrum 27on an extension 28 of the platform, whereby an upward movement of thelever will force the platform downward, thereby enabling the strength ofa person to be utilized to its greatest advantage in assisting hisweight to force the platform downward. The adjustability of theconnecting rod 22 in connection with the longitudinal slots 23 and 24enable the desired leverage to be readily obtained.

The platform is provided in advance of the ratchet wheel with a pivoteddepending spring actuated pawl 29 Y for actuating the ratchet wheel forwinding the cable on the drum. The pawl 29 is held in engagement withthe ratchet wheel by a curved resilient inner end 30 of a longitudinallymovable rod 3l, which is connected by a link 32 with an outer hingedsection 33 of the platform. The hinged section 33 is adapted to be swungupward against the main frame, in order to be out of the way after theoperation of winding up the weights is completed; and when swung upward,the hinged section 33 of the platform through the link 32 draws the pawl29 out of engagement with the ratchet wheel. As soon as the outer hingedportion of the platform is lowered to a horizontal position theactuating pawl 29 will be carried into engagement with the ratchetwheel. The longitudinally movable rod 31 is arranged in guide eyes 34 ofbolts, and is located on the lower face of the platform.

The lever 2O is provided with asliding outer section 35, whichtelescopes into the body of the lever when the winding mechanism is notin use.

It will readily be seen that the winding mechanism of the weight motormaybe readily adjusted to obtain the desired leverage to enable heavyweights to be conveniently raised; and that the power thus obtained maybe readily transmitted to any desired machinery or device to beoperated.

Changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.
